With reference to Fig. 1, disclosed soundproofing member 20 can be arranged on wall 22, limits openings 24. In sound insulationAssembly 20 is arranged in the example of vehicle, and described wall 22 can be the enging cabin that for example separates vehicle26 and the fire wall of the passenger compartment 28 of vehicle. At the present embodiment and without limitation, wall 22 is by sheet metal groupBecome and openings 24 receives and penetrates member 30, it can be one or more electric parts, mechanical part etc.For example,, and unrestricted,, penetrating member 30 can be a steering column or brake pedal and accelerator pedalContact. Certainly, wall 22 can be other positions on vehicle, for example, along transmission tunnel or main board,Or can be any wall of contiguous noise source, it may be, but not limited to,, engine. Should also be appreciated that, wall 22 can be any geometric format, comprises smooth, bending, rough and uneven in surface, wave etc., orFree state.

This openings 24 connects wall 22 completely and has open circumferential 32. Therefore, it should be understood that and pass throughPort 24 can be or can not be circular, because it is contemplated that other shape, and they are considered to thisWithin scope of disclosure. Wall 22 also present towards the first wall 34 of noise source and with the first wall 34The second relative wall 36. Therefore, the first wall 34 with the second wall 36 along the relative configuration of same wall 22.In the exemplary configuration shown in Fig. 1, the first wall 34 is towards the enging cabin 26 of vehicle and the second wallFace 36 is towards the passenger compartment 28 of vehicle. Penetrate member 30 and extend by the openings 24 of wall 22, to wearThoroughly between member 30 and open circumferential 32, limit a gap 38. This gap 38 often need to enable and/Or accelerate assembling, or provide enough spaces for penetrating member 30. But gap 38 also provides flankNoise path, by this path, noise can be propagated by wall 22. Feelings of a part for vehicle at wall 22Under condition, this flank noise causes passenger compartment 28 to have too much engine noise, road noise and/or sound of the wind.

The soundproofing member 20 of present disclosure has has advantageously reduced or eliminated by wall 22 and openings 24 and has passedThe noise of broadcasting. Continue with reference to figure 1-4, soundproofing member 20 comprises have one the against the second wall 36The separator layer 40 of one separator surface 42 and the second separator table relative with the first separator surface 42Face 44. The openings 24 of separator layer 40 general surrounding wall 22, and define the openings to wall 2224 open separator apertures 46. Separator layer 40 is at the first separator surface 42 and the second separator surfaceLaterally extending between 44, to limit the thickness 48 of separator, and separator periphery 50 and inner separator outsideExtending longitudinally between periphery 52, conventionally parallel with the second separator surface 44 with the first separator surface 42.By way of example and unrestriced mode, the thickness 48 of separator can boundary about 5 millimeters to about 30 millisRice, and can change with the degree of separator layer 40, limit the compression causing, example to hold local spaceAs air system plumbing, electric cableway etc. But separator layer 40 needs not to be flat or even thickness, instituteStating the first separator surface 42 can or can be not parallel with the second separator surface 44 yet.

Inner separator periphery 52 is shaped around separator apertures 46, and inner separator periphery 52 can be wrappedThe openings 24 of leg 22. Similar openings 24, separator apertures 46 can be or can not be circular,Because it is contemplated that other shape, and within they are considered to the scope of the present disclosure. Should also be understood thatSeparator layer 40 can be advantageously made up of sound-absorbing material. By way of example and unrestriced mode, described in formationThe sound-absorbing material of separator layer 40 can be any shaping fiber or foamed plastics, comprise polyester fiber withCotton, and/or the combination of these materials. Selecting the sound-absorbing material of separator layer 40 is in order to present and to imitateThe shape of wall 22, and keep this shape.

Soundproofing member 20 also comprises barrier layer 54, and it has against first of the second separator surface 44 and stopsFace 56 and second blocking surface 58 relative with the first blocking surface 56. Therefore, separator layer 40 serves as wall 22And air gap between barrier layer 54, make sound not pass to barrier layer 54 from wall 22. Barrier layer 54 limitsTo the openings 24 of wall 22 open stop hole 60. Barrier layer 54 is in the first blocking surface 56 and the second resistanceLaterally extending between block face 58, stop thickness 62 to limit, and stop outside periphery 64 with in stop peripheryExtending longitudinally between 66. By way of example and unrestriced mode stops that thickness 62 can boundary about 0.5Millimeter is to about 1.5 millimeters. But barrier layer 54 needs not to be flat or even thickness, described first stopsFace 56 can or can be not parallel with the second blocking surface 58 yet.

As best visible in Fig. 4, stop that periphery 64 can be larger than outer separator periphery 50, makes to stop outwardLayer 54 forms peripheral tabs 68, stretches out from outer separator periphery 50. Inner separator periphery 66 is in resistanceGear hole 60 is around shaped, and less than inner separator periphery 52. Therefore, stop that hole 60 is than separator apertures 46Little. Be made up of sound reflection material on barrier layer 54, means that barrier layer 54 makes to incide barrier layer 54Sound wave redirects. On the contrary, the sound-absorbing material of separator layer 40 absorbs and/or decays and incides separator layer40 sound wave. Barrier layer 54 also can be defined by the weight of material. For example, the material weight on barrier layer 54Can boundary about 0.050 pound every square feet to about 0.7 pound every square feet. By way of example but not limitThe mode of system, form the sound reflection material on barrier layer 54 and can be polypropylene (PP), polyvinyl chloride (PVC),Polyethylene (PE), vinyl acetate co-polymer (EVA), any other thermoplastic or thermosetting material and/or thisThe combination of a little materials.
